Specification of Letters Patent.

Patented April 24, 1906.

Application filed October 2,1905. Serial No. 281,028.

To aZZ whom it may concern:

Be it known that I, AUeUsT KAYSSER, merchant, residing at 12Feldbergstrasse, Hochstonthe\Iain, in the Kingdom of Prussia, Germany,have invented certain new and useful Improvements in Machines forCutting Stoppers, of which the following is a specification.

Hitherto stoppers of cork, for example have been made by cutting a cubeof the raw material and fashioning the cylindrical or conical stoppertherefrom either by hand or by a planing-machine, or the stoppers havebeen cut by a special boring-machine from a plate of the raw material.Both methods always occupy much time and entail much waste.

The present invention relates to a machine for cutting stoppers whichavoids these obj ections in that it cuts the stoppers by an adjustablenarrow band-knife from a rotating plate of the raw material sufficientin size to make a plurality of stoppers, the different conicities of thestoppers being obtained by varying the oblique position of the knife.

In order that, especially in the manufac ture of conical stoppers, lossof material may be reduced to a minimum, after each stopper has been cutthe plate of raw material is turned.

The accompanying drawings illustrate a machine made according to theinvention.

Figure 1 is a side elevation; Fig. 2, a plan, and Fig. 3 an endelevation. Fig. 4 shows how the conical stoppers are cut from a plate ofthe raw material.

The frame of the machine may be constructed in any suitable or desirableform;.

but it is essential that the means for rotating the raw material be solocated with reference to the frame or that the latter be so formed asto provide space for the rotation of a plate of raw material ofsufficient size to make a plurality of stoppers. In the machineillustrated in the drawings the main frame consists of a bed-plate A,upon which are mounted suitable standards and guides for the rotatingand cutting mechanism. Said bedplate is provided with a recess A, whichaffords the necessary space for the rotation of the plate of rawmaterial but said recess will not be necessary if the rotating means belocated a suflicient distance above the bedplate.

A fine band-knife a is stretched by means of clamps I) in a stirrup c,which is carried in two guides (Z c. The clamps b can be accuratelyadjusted by screws f with reference to a scale 9. The stirrup-frame c isdriven to and fro in the guides d e by a cranki and connectingrod h. Thecrank is revolved, through bevel-gear from the shaft Zr, carrying abelt-pulley 7c. The guides d 6 can be adjusted to bring the frame 0 tothe inclination proper for the conicity of the stopper by aid ofclamping-screws m, which pass through slots Z in the guides and holdthem to suitable supports (Z e, respectively.

The plate n, of raw material, from which the corks are to be cut, isheld between the two disks 0 0, of whicho is rotated by toothed gear pfrom the shaft 7t, and for this purpose is mounted 011 a shaft g, whichcan slide axially and can be connected by a clutch r with the shaft 8,which is turned by the said gear 1). By means of a lever t the disk 0can be withdrawn from the plate a, so that the latter can be removed. Aspring it keeps the disk 0 against the plate n. The disk 0 can rotate ina bearing carried by an upright o.

The operation of the machine is as follows: The lever t is turned todraw back the disk 0 against the pressure of spring a, and a plate of,say, cork is introduced between the disks 0 0, whereupon the lever t isleft free and the plate is firmly held between the disks. By adjustingthe guides d and e of the frame 0 by loosening the screws m and slidingthe guides l thereon the knife a is given the inclination proper for thedesired conicity of the stopper, while to produce a cork of the desireddiame ter the position of the knife is adjusted by adjusting the clampsb by turning the screws f. When the shaft 7c is set in rotation, thecrank "i gives a reciprocating motion to the frame 0 and knife a throughthe connectingrod 7i, while at the same time the gearing p drives theshaft s and through the coupling r the disk 0, so that the cork plate ais also revolved. When a stopper has been cut out, the plate a isremoved and turned over, so that closely against the place where thefirst stopper was out another is cut and the waste is very small. Thisis apparent from Fig. l. WVhen the knife a is adjusted parallel to thecommon axis of disks 0 0, cylindrical stoppers are cut.

Now what I claim, and desire to secure by Letters Patent, is thefollowing:

1. A machine for cutting sto pers out of a plate of raw material ofsufhcient size to make a plurality of stoppers, comprising a framecarrying devices for rotating said plate and providing space for itsrotation, and a slender band-knife of such proportions in cross-sectionas to permit it to describe a circle Within the plate to excise thestoppers, said knife being supported from its ends by means leavingspace for the plate 'to travel around the knife.

2 A machine for cutting sto pers out of a plate of raw material of scient size to make" a plurality of stoppers, comprising a frame'carryingdevices for rotating said plate and providing space for its rotation,and a slender traveling band-knife of such proportions in cross-sectionas to permit it to describe a circle Within the plate to excise thestoppers, said knife being supported by means leaving space for theplate to travel around the knife.

3. A machine for cutting sto pers out of a plate of raw material of s'cient size to make a plurality of stoppers, comprising a frame carryingdevices for rotating said plate and providing space for its rotation, aslender band-knife of such proportion in cross-section as to permit itto describe a circle Within the plate to excise the stoppers,

plate of raw material of su cient size to make a plurality of stoppers,comprising a frame carrying devices for rotating said plate andproviding space for its rotation, a slender band-knife of suchproportions in cross-section as to permit it to describe a circle Withinthe plate to excise the stoppers, said knife being supported from itsends by means leaving space for the plate to travel around the knife,and means for reciprocating said knife.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 2 1st day of September, 1905.
